Large-Scale High-Resolution Microelectrode Arrays Neurointerfaces
ISBN: 9783838104737 / Angielski / Miękka / 192 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Microelectrode arrays (MEAs)-based neuronal interfaces allow monitoring and stimulating neuronal networks both in vivo and in vitro. In vitro methodology is widely used to study and model at intermediate complexity learning and memory processes within a large neuronal network. Currently, commercially available MEA platforms for in vitro electrophysiology allow concurrent recording from at most 256 electrodes. However, dissociated neuronal cultures can consist of up to 100'000 cells within a monitored area of a few square millimeters. Thus, substantial spatial subsampling compromises the...

Lokale Konfiguration und partielle Aktivierung des FG-Effektes
ISBN: 9783838125411 / Niemiecki / Miękka / 184 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Formgedachtnislegierungen (FGL) besitzen den Charme der Realisierbarkeit einfach aufgebauter, leichter und gerauschlos arbeitender Aktoren. Aufgrund der komplexen Eigenschaften, der fehlenden Simulations- und Auslegungswerkzeuge und der fehlenden Normen sind FGL-basierte Produkte jedoch bisher nur selten zu finden. Unternehmen scheuen haufig die Risiken, die mit einer Individualentwicklung verbunden sind. Um diesen Missstand zu beseitigen, ist es notwendig, standardisierte Aktorsysteme, wie sie beispielsweise bei Elektromagneten oder Elektromotoren vorzufinden sind, bereitzustellen. Das...

Robotic assembly using IPMC for compliance in SCARA & 4-bar mechanism
ISBN: 9783639517644 / Angielski / Miękka / 196 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Robotic assembly is an important process in the electronics and automobile industries in which small parts like pins etc. are assembled together. Humans are adept at assembly but advanced robots still find it difficult to assemble small components because during assembly there always exist errors in the positioning of parts. The error emanates from the robotic system itself or from the manufacturing processes used to make the parts. One way to perform successful assembly is by providing some compliance that can accommodate the errors in parts positioning. In this book, active compliance is...

Kinetic Theory Approach for the Determination of Rate of Evaporation
ISBN: 9783639519396 / Angielski / Miękka / 192 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This work is a report of study carried out on the rate of evaporation from a liquid surface. In the theoretical approach, the Boltzmann transport equation with the simplified collision terms as modelled in the BGK equation was made use of. This collision term is taken to be the difference between the Maxwellian distribution of molecular velocities under equilibrium condition and the actual distribution function under non-equilibrium condition. The problem was formulated for both single component and two component cases. The resulting Itegro-differential equations were simplified to a set of...

Kinematic structure of mechanisms
ISBN: 9783639701272 / Angielski / Miękka / 172 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Kinematic structural studies play an important role in the design of mechanisms. These studies consider only the interconnectivity pattern of the individual links and hence are unaffected by the changes in the geometric properties of the mechanisms. This work focus on the three classical problems in this area: synthesis of all non-isomorphic kinematic mechanisms; detection of all non-isomorphic pairs of mechanisms; and, classification of kinematic mechanisms based on type of mobility. This work illustrates the successful use of techniques from graph theory and combinatorial optimization to...
